"There’s a chance that some of the people in the youth group attend Stanwood schools, and that’s why Snohomish County is involved," said Jo Hofmann, MD, Deputy Health Officer and Director of the Communicable Disease Division at Snohomish Health District.

Dr. Hofmann has advised the Stanwood School District of the following exclusion criteria for students who have been exposed to measles and may be insufficiently immunized:

Students who have documentation (a written record) of two doses of measles vaccine, or who have had a blood test that shows immunity to measles may continue to attend classes.

Students who have documentation (a written record) of one dose of measles vaccine may return to class after they have received a second dose of measles vaccine.

Students who have no documentation (a written record) of measles vaccine will be excluded from the school until 21 day s after the last reported case of measles in their school.

So far no other cases of measles have been reported in either Island or Snohomish county. Exclusion criteria will be extended to all school staff and students if a second case of measles is identified among staff or students at any school.

For more information about measles, Island County residents should call 360.387.3882; Snohomish County residents should call 425.339.5225.

Established in 1959, the Snohomish Health District works to improve the health of individuals, families and communities through disease prevention, health promotion, and protection from environmental threats.
